To all whom it may concern:

Be it known that I, JAMES L. COFFIELD, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Driving Mechanism for Glothes-Wringers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to driving mechanism for clothes wringers and has for its object to provide a mechanism for driving the wringer rollers in either direction depending upon the position of the tub in connection with which the wringer is operated.

In the use of clothes wringers it often becomes necessary to wring clothes from two tubs between which the wringer is located.

Also it is common practice to mount the wringer in such a manner that its operation may be required to be carried on in different positions in which case the rollers must be operated in either direction.

In the accompanying drawings, Figure 1 is an elevation of an ordinary form of clothes wringer having my reversing driving mechanism applied thereto; Fig. 2 is a stop view of the roller; Fig. 3 is a side elevation of the driving mechanism with part of the wringer frame broken away and showing one position of the gearing; Fig. 4 is a similar elevation showing another position of the gearing; and Fig. 5 is a sectional view on the line 5-5 of Fig. 3. p

In a detailed description of the invention, reference characters indicate corresponding parts.

Referring more particularly to the drawings, 1 designates the various parts of the frame of the wringer in which are yieldingly supported rollers 2 and 3. The lower roller 3 is the driving roller of the two and this roller is provided with a spur gear 14 which is fixed to the shaft 15 of said roller and lies on the outside of a plate 20 which is secured on one side of the wringer frame. Between the gear 14 and'the plate 20 a swinging plate 9 is pivoted, the journal 15 of the roller 3 forming the pivot thereof. The

plate 9 has pivoted to it spur gears 6 and 7 either of whlch is adapted to mesh with the spur gear 14 according to the direction of rotation it is desired shall be given the wrlnger rollers. 5 designates a spur gear mounted on the driving shaft 4 in a position to mesh with either of the gears 6 and 7. The driving shaft 4 is driven from any suitable motor such as an electric motor or water motor. The swinging plate 9 which supports the gears 6 and 7 is shifted on its pivot 15 to bring either of the gears 6' and 7 in mesh with the driving gear 5 and in and out of mesh with the gear 14, or as shown in Fig. 3, the plate 9 may be shifted to a position to entirely free both of the gears 6 and 7 from meshing with the driving gear 5. The swinging plate 9 is shifted to effect such engagement and disengagement ofthe gears 6 and 7 by means of a hand lever 10 which is connected at one angle of the plate 9 by a pivot 13. The lever 10 is provided with a transverse slot 12 on a slight are through which the reduced portion of a pin 8 projects. The pin 8 projects rigidly from the plate 20 and the lever 10 rests against the shoulder thereof which is provided by reducing the diameter of the pin, as shown in Fig. 5. The outer end of said pin terminates in a head 11 and the reduced portion thereof supports a clamping button 18 having an inner rounded surface which is adapted to enter any of the three recesses 19 that are formed in the outer'side of the slotted portion of the lever 10. A coil spring 17 surounds the reduced portion of the pin between the fixed head 11 and the movable button 18 and exerts a pressure against the said button to normally maintain it in either of the recesses 19 and to thereby hold the lever 10 in any of its positions. The operation of the lever 10 to shift the gears 6 and 7 in reversing the direction. of the wringer roller 3 will be readly understood. The said lever is moved to the position shown in Fig. 4 in order to transmit the motion from the driving shaft 4 to the wringer roller 3 in one direction, as indicated by the arrow, and said lever is shifted to the other extreme position to that shown in Fig. 4 to reverse the drive. In that case the spur gear {3 will mesh with the spur gear 14 and the gear 7 will unme'sh with the gear 14 and mesh with the drivin ear 5. When the lever 10 is moved to the eentral position,

copies at this patent may be obtained for as shown in Fig. 3, the gearing will be thrown entirely out of mesh with the driving gear 5. The necessary force applied to the handle portion of the lever 10 will cause the holding button 18 to yield suitliciently to pern'iit the lever to be moved to any of the positions at which time the button 18 will enter the recesses 19 in the lever to hold the same in such position.

Having described my invention, I claim.

1. In a reversible driving gear for clothes Wringers, the combination with a Wringer roller having a driving gear attached thereto, of a swinging plate pivoted to the axis of said Wringer roller, two spur gears pivoted to said swinging plate in positions to alternately engage the gear on said wringe-r roller, a driving gear arranged to alternately engage the gears on said swinging plate to impart reversed movement to the wringer roller, a lever pivoted to said swinging plate and by means of which it is shifted to cause one or the other of the gears thereon to intermesh With the gear on the wringer roller and said driving gear, and

means for holdin said lever in the position to whlch it is shifted in so changing the relative I positions of the 2. In a reversible driving gear for clothes U Wringers, the combination with a wringer roller, "of a gear attached thereto, a reetangular swinging plate pivot-ed at the axis of said gear, a driving gear, reversing gears mounted on said swinging plate in positions to alternately engage said driving gear and the gear attached to the wringer roller to drive the Wringer roller in opposite directions a lever pivoted to said swinging plate by ineansof which the gears between the driving gear and the gear of the Wringer roller are shifted, a button adapted to hold said lever in any of the positions to which it is shifted, a'rigid pin penetrating said lever and supporting said button, and an expansion spring engaging said button, substantially as specified.

In testimony whereof I afliX my signature, in presence of two Witnesses.
